  Hereinafter, preferred embodiments for carrying out the present invention will be described. A massage device 1 according to an embodiment of the present invention is a massage device for massaging a face or head, as shown in FIGS. 1 (a) and 1 (b) and FIGS. 2 (a) and 2 (b). Furthermore, the elongate grip part 2, the fixed shaft part 3 fixed to the grip part 2 and extending from one end thereof, and the skin contact part arranged in a rotatable state around the tip end part of the fixed shaft part 3 4 is provided. FIG. 1A schematically shows an electric machine member and its electric wiring (broken line portion) with respect to the internal configuration of the grip portion 2.

  The grip portion 2 is a long, ie, generally long cylindrical box, and has a selection switch 21 exposed (exposed) on the bottom so that it can be operated from the outside. In addition, the grip portion 2 accommodates batteries 22 and 22 ′, thermostats 23, a motor 24, and the like that are electromechanical members. The batteries 22, 22 ′ are operated by operating the selection switch 21 to energize a heating element 32 to be described later in order to heat the fixed shaft portion 3 to generate heat, or to the motor 24 to vibrate the fixed shaft portion 3. Energize to rotate. The rotational movement of the motor 24 generates vibration, and the vibration is transmitted to the fixed shaft portion 3 through the vibration transmitting means 24A. In addition, the holding part 2 is formed with a protruding part 2 a surrounding the fixed shaft part 3 up to the middle part thereof.

  In this embodiment shown in FIG. 1A, it is assumed that two states, ON and OFF, can be selected by the selection switch 21, and the fixed shaft portion 3 is heated and vibrated in the ON state. is there. More specifically, between the positive electrode of the battery 22 and one terminal of the thermostat 23, between the other terminal of the thermostat 23 and one terminal of the heating element 32, and between the other terminal of the heating element 32 and the negative electrode of the battery 22 ′, respectively. Electrical wiring is provided, and electrical wiring is provided between the positive electrode of the battery 22 and one terminal of the motor 24, and between the other terminal of the motor 24 and the negative electrode of the battery 22 '. Electrical wiring is provided between one terminal of the switch 21 and between the other terminal of the selection switch 21 and the negative electrode of the battery 22. When in the off state (the state in which the selection switch 21 is slid to the right in the figure), the two batteries 22 and 22 'are not electrically connected, and in the on state (the state in which the selection switch 21 is slid to the left in the figure). ), The two batteries 22 and 22 'are electrically connected, the heating element 32 and the motor 24 are both energized, and the fixed shaft portion 3 is heated and vibrates.

  The selection switch 21, the electromechanical member, and the electrical wiring thereof can be appropriately changed according to the specifications. For example, it is possible to provide two selection switches 21 and heat or vibrate the fixed shaft portion 3 in the ON state. Further, the batteries 22 and 22 'can be changed to one or three or more primary batteries or rechargeable batteries, and can be recharged in a mounted state.

  The thermostat 23 is for controlling the surface of the skin contact portion 4, that is, the portion in contact with the skin, to have an appropriate temperature (for example, a maximum temperature of about 40 to 45 ° C.). It is disposed in contact with the main body 31. The thermostat 23 controls energization of the heating element 32 according to the temperature detected by the temperature detection portion.

  The fixed shaft portion 3 includes a cylindrical fixed shaft main body 31 (for example, made of aluminum or stainless steel) having high thermal conductivity, a heating element 32 that generates heat when energized therein, a fixed shaft main body 31, and a later-described Bearings 33 and 33 ′ provided between the carbon molded bodies 41 and a fastening member 34 that is detachably attached to the tip of the fixed shaft main body 31 are provided. As the heating element 32, for example, a nichrome wire covered with an insulating material can be used by reciprocating from the vicinity of the base end of the fixed shaft main body 31 to the vicinity of the tip end. The fixed shaft main body 31 is heated by the heating element 32 to transmit the heat to the skin contact portion 4, and the temperature is detected by the thermostat 23 described above. The bearings 33, 33 ′ are provided at both ends of the carbon molded body 41 so that the inner surface is in contact with the fixed shaft main body 31 and the outer surface is in contact with the carbon molded body 41. Since the structures of the bearings 33 and 33 'are the same as those of known bearings, description thereof is omitted. The fastening member 34 keeps the skin contact portion 4 from coming off from the distal end side of the fixed shaft main body 31 and protects the bearing 33 ′ on the distal end side.

  When the user presses the massage tool 1 against the skin and makes a reciprocating motion, the skin contact portion 4 follows and rotates. The skin contact portion 4 is mainly composed of a carbon molded body 41 that receives heat from the fixed shaft portion 3 and transmits it to the surface to be brought into contact with the skin.

The carbon molded body 41 is formed in the following manner, in which the carbon crystal structure that is dense and arranged by firing is formed isotropically (regardless of the direction), and is formed integrally as a whole. be able to. That is, about 5% by weight of a binder is added to graphite or carbide (such as bamboo charcoal) carbon powder to be solidified, and then isotropically pressed with water pressure or the like to form a predetermined lump (for example, a rectangular shape). And it heats in the state which oxygen deficient, and baks over about 2500 to 3500 degreeC over a long time. In this state, the raw material carbon powders are bonded to each other, and the carbon is crystallized (graphitized and shaped carbonized). The binder is volatilized at about 1000 to 1200 ° C. during the temperature increase. Thereafter, heating is stopped, the temperature is lowered, and processing is performed into a desired shape. Since the binder is volatilized in the carbon molded body 41 thus completed, almost 100% (99% or more) is a carbon material. The bulk density (bulk specific gravity) is 1.77 Mg / m ³ or more.

  Since the carbon molded body 41 has an integral crystal structure, it has high physical strength and high thermal conductivity (about 100 to 140 W / (m · K)). Moreover, the amount of far infrared rays radiated is large (see FIG. 3), and the higher the temperature, the larger. FIG. 3 shows far-infrared radiation characteristics of a carbon molded body of 25 × 25 × 2 (mm) manufactured in the same manner as the method of manufacturing the carbon molded body 41. The solid line is the carbon molded body, and the broken line is the black body radiance. The analyzer used was a JEOL Fourier transform infrared spectrophotometer JIR-5500 type / infrared radiation unit IR-IRR200, and the measurement temperature was 50 ° C.

  As shown in FIG. 1B, the carbon molded body 41 has a substantially columnar shape, and an insertion hole 41a into which the fixed shaft portion 3 is inserted is formed so as to penetrate through the position of the central axis. Further, in the vicinity of both openings of the insertion hole 41a, concave portions 41b and 41b 'into which the above-mentioned bearings 33 and 33' are fitted are formed. For example, the carbon molded body 41 can have an outer diameter of about 15 to 30 mm and an axial length of about 30 to 50 mm. The inner diameter of the insertion hole 41a is slightly larger than the outer diameter of the fixed shaft portion 3 (for example, about 0.1 mm) so as not to hinder heat conduction from the fixed shaft portion 3 to the carbon molded body 41 as much as possible.

  The carbon molded body 41 can employ various shapes so as to facilitate contact with the skin. For example, it is possible to form a plurality of annular grooves 41c as shown in FIG.

  The carbon molded body 41 of the skin contact portion 4 is provided with a diamond-like carbon (DLC) coating 42 (for example, a thickness of about 2 to 4 μm) on the surface thereof. The diamond-like carbon film 42 is formed by vapor phase growth by plasma CVD, PVD, or the like to form carbon having a crystal structure, has good adhesion to the carbon molded body 41, and is hard. In order to obtain bactericidal properties, fluorine and / or silver can be mixed during the vapor phase growth of diamond-like carbon.

  The usage method of this massage tool 1 is as follows. That is, the user operates the selection switch 21 while holding the grip portion 2 by hand, heats and vibrates the fixed shaft portion 3, presses the skin contact portion 4 against the skin, and reciprocates with an appropriate force. To massage the skin.

  Following this reciprocating motion, the skin contact portion 4 rotates. The skin contact portion 4 is less likely to be worn or damaged because the carbon molded body 41 has a high physical strength and the coating 42 is hard. In addition, since the carbon molded body 41 and the coating 42 are the same as the constituent substances of the organic matter that forms the human body, the carbon molded body 41 and the coating 42 are familiar with it when they come into contact with the skin, and are highly safe to the human body. Since they are not metals or plastics, of course, they do not cause metal allergies or chemical allergies.

  When the fixed shaft portion 3 is heated by the operation of the selection switch 21, the heat of the fixed shaft portion 3 is conducted to the carbon molded body 41 of the skin contact portion 4, and the temperature becomes high. The carbon molded body 41 directly transfers heat to the skin by heat conduction and emits far infrared rays whose amount increases as the temperature increases. This far infrared ray heats the deep part near the skin. Since the temperature in the vicinity of the skin is efficiently increased by the conduction heat and the radiant heat of far-infrared rays, the blood circulation in the vicinity of the skin can be further promoted by the synergistic effect with the pressure by the skin contact portion 4.

  Further, since the carbon molded body 41 has a high thermal conductivity, the temperature drop from the insertion hole 41a into which the fixed shaft portion 3 is inserted to the surface is small. Therefore, it is not necessary to raise the temperature of the heating element 32 so much, and the accuracy of temperature control by the thermostat 23 in contact with the fixed shaft main body 31 is improved.

  Further, when the fixed shaft portion 3 vibrates by the operation of the selection switch 21, the vibration is transmitted to the vicinity of the skin via the skin contact portion 4. This vibration can further promote blood circulation in the vicinity of the skin.

  As mentioned above, although the massage tool 1 which concerns on embodiment of this invention was demonstrated, this invention is not restricted to what was described in the above-mentioned embodiment, In the range of the matter described in the claim of a utility model registration Various design changes are possible. For example, the massage tool 1 may not be provided with a vibration function in some cases. In this case, the motor 24 and the like are not necessary.
